Landslides are one of the most frequent natural disasters in Indonesia, especially in West Java Province, this is due to the geographic and climate conditions that are very supportive. Parongpong area, especially in Cihanjuang village is one of the areas with the highest landslide potential. Knowledge of potential landslide characteristics is very important to know the appropriate precautions and avoid the occurrence of casualties. This study aims to determine the area of slideplane landslide. One of the geophysical <br /> <br /> <br /> methods that can be used in the research of landslide potential is the resistivity method, this method is <br /> <br /> <br /> very sensitive to the water content below the surface which is one cause of the occurrence of an landslide. <br /> <br /> <br /> The configuration used is the Dipole-dipole configuration on four paths using the OCO model <br /> <br /> <br /> resistivitymeter model McOHM-21. Each line has a length of 75 m to the east-west direction and 28 m to <br /> <br /> <br /> the north-south direction. The line lies on a hill with a slope of about 15 degrees. Based on resistivity result and geological condition, The research area in Cihanjuang village consists of three layers of lithology area which is interpreted as tuffic sand as landslide material, clay as field of slip and volcanic breccia, with resistivity value is 73,8 ohm m &#8722; (>556) ohm m, 5 ohm m &#8722; 19,5 ohm m 114 ohm m. The type of landslide that have the potential to occur in the research area is a rotational landslide.
